A return to the 'sustainable' population levels of the 1900's!!?
Apart from the small issues of the abrupt departure of eight billion souls, there's the small matter of the circumstances in which those levels would be reached!
"There are some levels of existence we are prepared to accept."No there isn't. I don't think anyone really has a clue about how conditions will degrade with just one of these doozies breathing down our necks, let alone five (or even the four that's prompted the 'return to the good old days' meme).- The Architect from 'The Matrix: Reloaded'
Well, maybe some do. That's why the grief rockers like that raptureholic 'IgDrip' are already spouting such gibberish about 'coming on over' (to the right hand side of the GEAS population graph)
They've given up. Worse, I can see they're going to be running malicious interference on those who haven't. (I thought we'd got over that a decade ago?)
